MR Imaging of Bone Marrow About the Knee

ABSTRACT

Magnetic resonance imaging (MRI) is the imaging modality of choice used to assess bone marrow not only in the knee but throughout the musculoskeletal system. Its ability to characterize marrow makes it an essential imaging tool in the evaluation of patients with suspected marrow pathology. In this article, we describe the MRI appearance of normal bone marrow and its pathology in the knee.

KEYWORDS

Trauma - marrow - injury - infection - arthritis
